INSTALLATION PROCEDURE FOR THER-A-GRIP 1070:
Step 1
:
Make sure the chip surface is clean and free from any possible contaminants.
Wipe surface with industrial solvent, e.g., isopropyl alcohol, acetone.
Step 2:
Peel off the blue mylar embossed liner from the tape. Center the heat sink on the chip
and apply one of the following recommended temperature/pressure options:
TWO-PIN HEAT SINKS FOR BALL GRID ARRAY APPLICATIONS
Aavid’s two-pin heat sink is designed for IC’s in
Ball Grid Array packages, and incorporates two
captive spring-loaded pins.Two-pin heat sinks
are ideal for applications that require robust
attachment for vertical-mounted boards, such
as in telecommunications, automotive, and
computer systems,
Aavid’s design breakthrough saves approximately
40% of the board space compared to four-pin
versions.The two-pin heat sinks fit standard
motherboard hole pattern for the AGP and PCI
chip sets.
